BOOSTER-MOTOR SUPPORT.

Application filed September 3, 1926. Serial No. 133,405.

point where the truck and superstructure.

are pivoted to each other.

Additional objects of my invention are to adapt the truck and superstructure framing for such booster motor support arrange-' ments and to transmit the superstructure load to the truck in such a manner that the 2 truck frame will not have to be increased in depth at a point intermediate its sides in order to s'upportthe booster motor, it being desirable to keep the depth of the truck frame at a minimum in order to avoid raising the center of gravity of the tender tank orother superstructure or to avoid reduction in the capacity of the same.

In the accompanyin drawings which illustrate a selected. em odiment of my inventibn- Figure 1 is a longitudinal sectionthrough the center of a tender'underframe and four wheel truck frame, other truck parts and the-booster motor being indicated. I

Figure' 2 is in part a transverse section through the center of the truck frame, adjacent parts of the underframe being indicated, and-in part an end view of the truck. The truck comprises the usual wheels and axles having journal boxes which carry the double equalizers l provided with s ring seats and brackets 2; the truckframe ing supported by the equalizers through hangers 3 and leaf springsfi. Undue tilting of the truck frame is "prevented by the coil iprings 4. .The truck frame. is preferably ormed of a one-piece casting and includes wheel pieces 5' having integral pedestal forming portions and connected by transverse transoms 7 and 8. The wheel pieces are provided with upwardl facing side bearing ockets 9 through w 'ch the superstructure lbad is transmitted directly to springs 6 and 4, thereby which pivotally supports a link 15 which of the weight of the rear end of the motor 7 exerted at the'end of a lever corresponding t avoiding the necessity of de bolster sections for carrying the load transversely of the truck. This enables V v the transoms 7 to be used only as transverse ties' for the frame and as means for 'centermg the underfranie bolster 10 which is providedwith downwardly facing side bearings 11.

The truck transoms 7 and the underfra'me bolster 10 have cooperating center plate elements 12 and 13, respectively, which are annular in shape and provide a large opening about the axis of the pivotal connection between the truck and underframe. Above this opening .the bolster side walls are provided with bearings for a horizontal pin 14 passes downwardly through the center plate elements 12 and 13 and at its lower end carries a bearing-16 having a spherical contour and forming a support for the bed of the booster motor 17. Thismotor is operatively 75.

connected to the righthand axle of the truck and is adapted to drive the latter when the locomotive isstarting or laboring under a 7 heavy load. The side walls of the bolster are connected by longitudinal ribs 18 on each side of the bearingsfOr pin 14 and these-ribs are connected over the top of the link 15 and form a downwardly opening pocket for the pin andlink'.

The construction illustrated and described permits the booster motor to swing about the center of the truck with the axle to which it is connected and also permits the motor to tilt in vertical planes, extending longitudinally and transverselyof the center line of the truck, as may be required b vertical movement of one or both ends of t e axle in their respective pedestals. Supportin the motor from the superstructure .under ame at the pivotal connection between the truck and superstructure results in a'substantially stationary position of the portion of the motor-supported by link 15. When the truck swivels, the motor bearin s 19 on the axle 1 are not called upon to shift the portion of the motor supported by link 15 andtherefore are not required to overcome the inertia to the length of the motor as woul be the case if the rear support of the motor were spaced from the truck center plate.v

. The structure can be made without increasing the depth of the transoms or under 11 frame and forms a simple and efiective method of supporting a booster motor applied to a tender truck. I

The various advantages of this structure may be similarly attained by the use of numerous modifications of the details of my construction and I' contemplate the exclusive use ofsuch modifications as fall within"- the scope'ofthe principles of my invention as expressed .in my c'l'aims.'
